National Gallery is still the same, free admission, just a few more donation boxes than before, placed in the main roads, visitors can invest money at any time. I was very happy to see that my favorite Ben Matu was still hanging in the old place. As soon as I opened the door of the hall, I saw that it was about to leap forward. There are also some Van Gogh, Picasso's authenticity, all priceless treasures are gathered in dozens of square meters, people feel incredible, and even began to doubt, this can not be true!!! In fact, I really went to talk to the staff patrolling the museum and asked them how to ensure their safety and protection from intentional or unintentional damage by many visitors. There is only one rope, one foot above the ground, standing between the painting and the visitors, but if you bend down and move forward, you can almost paste the picture on it. Occasionally, some people take pictures with flashlights. These breaths will inevitably have an impact on them. The staff told me that there was no way. In order for art lovers to really have close contact with these treasures, the gallery could only do its best to protect them, but it was impossible to close the paintings and cover them with glass frames or something. That would be a bad experience to visit. So every exhibition hall is patrolled, problems are found at any time, and inappropriate behavior is stopped at any time. Compared with the vast visitors to the British Museum, the exhibition experience of the National Gallery of Art is a clear stream. It can stay, stand, sit, side, near and far in the same space as its favorite paintings, and appreciate it carefully from all angles.
